I installed Windows 10, now 3dmark won't launch. When I go into Steam and click launch a small window pops up for 1/10 of a second and goes away and that's it. It just won't launch. The same thing happens when I click the start menu in the lower right corner of the screen and click settings. A window pops up for a small fraction of a second and goes away. If anybody could help me I'd be extremely appreciative.
